What we’re about

For those interested in learning what a Home Energy Audit is:
FREE WORKSHOP: Witness a live HOME ENERGY AUDIT after retrofit at the 1981 SERI (NREL) designed home of John Avenson. John is obtaining his HERS rating to measure the success of his super insulation retrofit finished in 2015. This house received the 2014 CGBG award for best energy saving retrofit. John hopes the blower door test will come in well under 1 air exchange per hour at the ACH50 level. To put into perspective, most older code homes are over ACH50 of 7 meaning the furnace would have to re-heat the air >7 times in one hour.
Also: Enjoy Hands-on with John's Infrared FLIR camera.
- Tour John's 1981 SERI (NREL) designed home which has NO FURNACE and still stays warm all winter, also with voice control and electric shades.
